What is a Data Registry?
 A place to keep facts about characteristics
of data that are necessary to clearly
describe, inventory, analyze, and classify
data
 Supports data sharing with cross-system
and cross-organization descriptions of
common units of data
 Assists users of shared data to have
common understanding of the meaning,
representation, and identification of a unit
of data

What is the EDR?
It is a single,
comprehensive,
authoritative source
of information about
environmental data.
The EDR is available
electronically via the
World Wide Web.

 Enable data sharing, data integration, and
data comparability
 Provide a metadata repository - a central
information source about Agency data
